To raise funds and awareness for Special Olympics Hawaiʻi, volunteer, off-duty law enforcement officers will take their duties to new heights for this year’s 18th annual Cop on Top. During the event, from Aug. 23-25, participants will rise to the occasion accepting donations from atop 10-foot scaffolds fronting all Hawaiʻi Walmart stores [except Downtown Honolulu], the two Oʻahu Sam’s Club locations, as well as shopping centers around Oʻahu.
